The MEDUSA is a mobile sculpture, that engages with the subjects of privacy and publicity, as well as with the mutation, utilization and function of urban space. Throughout the course of 'flippat', the MEDUSA is placed in Gustav Adolfs Torg, downtown Malmö. As a stranger it occupies and disturbs habitual relationships and connections. Generally this kind of installation has the possibility to adapt itself to the different environments and context, even including features of the landscape (i.e. a tree, a column etc.) inside its middle-core the MEDUSA structure is blending with its surroundings.
